    Maximize solar efficiency with Renogy's Rover 40A MPPT controller and BT-2 wireless module. The controller's dual-peak tracking harvests 99.9% energy even in shade, while the BT-2 enables real-time adjustments of lithium/gel charging curves via DC Home App (82ft range). Built for extreme climates (-40°F to 185°F) with IP54 waterproof rating and lightning surge protection, this duo auto-compensates temperature for AGM/lithium batteries. Monitor 1-year performance logs on the LCD or app, control inverters/DC loads remotely, and daisy-chain via RS485 ports for solar farms. The controller's die-cast aluminum housing dissipates heat from 40A arrays, while the BT-2's 16.4ft cable allows hidden RV/boat installations. Features lithium reactivation mode, 0.04W standby drain, and Modbus industrial protocol—certified for FCC/ISED with 24/7 support
